Consider the process a(l) → a(g) 73°c 161°c, which is carried out at constant pressure. the total δs for this process is known to be 75.0 j·k−1·mol−1. for a(l) and a(g), the cp values are 75.0 j·k−1·mol−1 and 29.0 j·k−1·mol−1, respectively, and are not dependent on temperature. calculate δhvaporization for a(l) at 125°c (its boiling point).

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
